Image noise, that horrible side-effect of capturing digital images at higher ISO sensitivities, could one day be a thing of the past, thanks to artificial intelligence.

Researchers at Nvidia, working with another set of researchers from Aalto University and Massachusetts Institute of Technology (MIT) have developed an AI program that can remove noise from images.

Reducing the effect of image noise in post-processing programs such as Photoshop has been possible for a while, but this is a whole different ball game.

While previous research involved training a neural network to remove noise from images using example pairs of noisy and clean images, this new AI has been trained using only corrupted photos.

Remove artifacts, noise, grain

This means that without ever being shown what a noise-free image looks like, the AI can remove artifacts, noise and grain to enhance your photos.

“It is possible to learn to restore signals without ever observing clean ones, at performance sometimes exceeding training using clean exemplars,” the researchers have stated in their paper.

“[The neural network] is on par with state-of-the-art methods that make use of clean examples – using precisely the same training methodology, and often without appreciable drawbacks in training time or performance.”
